A nurse is collecting data from a client about range-of-motion for various joints. Which of the following should the nurse identify as an example of a ball and socket joint?
Ankle
Shoulder
Knee
Metacarpophalangeal
The Correct Answer is B
A. Ankle is incorrect. The ankle is a hinge joint, which allows for movement in one plane (up and down), not the multidirectional movement characteristic of a ball and socket joint.
B. Shoulder is correct. The shoulder joint is a ball and socket joint. This type of joint allows for movement in multiple directions, including flexion, extension, abduction, adduction, rotation, and circumduction.
C. Knee is incorrect. The knee is a hinge joint, allowing for flexion and extension but not the wide range of motion that a ball and socket joint offers.
D. Metacarpophalangeal is incorrect. The metacarpophalangeal joints (knuckles) are condyloid joints, which allow for movement in two planes but not the full rotational movement of a ball and socket joint.

Correct Answer is C
Explanation
A. Having the client point his toes before inserting his foot into the stocking is incorrect. The nurse should instruct the client to keep the foot in a neutral position to avoid unnecessary pressure on the toes or veins.
B. Removing the stockings once every 24 hr is incorrect. Antiembolic stockings should typically be removed and reapplied at least once per shift to allow for skin assessment and hygiene. They should not remain on for 24 hours continuously.
C. Elevating the client's legs for 5 min prior to applying the stockings is correct. Elevating the legs helps promote venous return by reducing swelling in the lower extremities. This makes the application of antiembolic stockings more effective and more comfortable for the client.
D. Rolling the top of the stocking down so it fits snugly above the client's calf is incorrect. The stockings should be applied smoothly and without folds to avoid restricting circulation. The top should not be rolled down as it can create pressure points
Correct Answer is C
Explanation
A. "Eat 40 milligrams of protein-rich foods per day.": Protein intake is important during pregnancy, but 40 milligrams is an unusually low amount. The recommended amount is generally higher, around 71 grams of protein per day during pregnancy.
B. "Increase your dietary intake by 500 calories per day.": The general recommendation for calorie increase during pregnancy is about 300 calories per day, not 500. 500 calories per day may be recommended in specific situations, but it is not the typical guideline.
C. "Consume 600 micrograms of folic acid per day.": This is the correct recommendation. The CDC and other health guidelines recommend that pregnant individuals consume 400-600 micrograms of folic acid daily to prevent neural tube defects.
D. "Limit your caffeine intake to 700 milligrams per day.": Caffeine intake should generally be limited to around 200-300 milligrams per day during pregnancy, not 700 milligrams, as high caffeine intake can have adverse effects on pregnancy outcomes.
